Connecting Coral Reefs

Coral reefs are some of the most endangered ecosystems on the planet that are home to beautiful wildlife and provide food to many people living on the coast. So how do you protect the reefs without cutting off communities from their food source?...
A shell placed in seawater with increased acidity slowly dissolves over 45 days.

Shell Dissolves in Seawater

Over a 10-year period, NOAA scientists have collected 72,000 seawater samples, and their data show that the ocean is becoming more acidic because of climate change . That small change in acidity is enough to dissolve the shells of animals like this...
UV light illuminates growth rings in a cross-section of 44-year-old Primnoa resedaformis coral found about 400 m (1,312 ft) deep off Newfoundland.

Coral Growth Rings

Ultraviolet light illuminates the growth rings in a cross-section of a 44-year-old deep-sea coral ( Primnoa resedaeformis ) collected off the coast of Newfoundland at about 1,300 feet (400 meters). Similar to tree trunks, cross-sections reveal coral...
A male great hammerhead shark swims just below the surface of the water in the Bahamas at sunset.

Hammerhead Shark at Sunset

A male great hammerhead shark swims in the Bahamas at sunset. Scientists debate the purpose behind these sharks' hammer-shaped heads. A commonly accepted theory is that the shape allows the shark to scan a wider area of the ocean through its sensory...
An underwater photo of coral recovering from a bleaching event.

Resilient Coral

Is it lights out for corals once they have experienced a bleaching event? Not necessarily. This photo shows a coral reef near Bocas del Toro, Panama that is in the process of recovering from a mass bleaching event that occurred in the summer of 2010...
A pile of bycatch species.

A Net Full of Bycatch

Bycatch, or accidentally caught species, can make up a very high percentage of the haul in shrimp trawl nets. However, some of these “trash” species are now being used, rather than discarded, and new technologies can reduce the catch of non-target...
A light brown gecko with medium brown markings, standing on a dead and weathered tree trunk.

Island Leaf-Toed Gecko

The Island Leaf-Toed Gecko ( Phyllodactylus insularis ) is one of several species of geckos that live in the mangroves of the Caribbean’s Mangal Cay. More about mangroves can be found in our Mangroves overview.
An algal bloom, also known as a red tide, has converted the ocean's surf to a red color

Red Tide

In the ocean, microscopic forms of algae, known as dinoflagellates , can "bloom" into dense patches near the surface, often referred to as "red tides." Some of these harmful algal blooms (HABs) are dangerous, producing toxins that can kill marine...
The fluorescent shortnose greeneye fish.

A Shortnose Greeneye Fish Aglow

Under white light, this shortnose greeneye fish ( Chlorophthalmus agassizi ) looks unimpressive. But, in dim blue light—the type usually seen at depth—it shows its true fluorescent colors. NOAA scientists collected this specimen during a 2004...
An image of a squid radula from a scanning electron micrograph.

Close-up of Giant Squid’s Radula

This image from a scanning electron micrograph magnifies the tiny teeth that cover the surface of the giant squid’s tongue-like organ, or radula . Seven rows of sharp teeth help direct tiny pieces of food down the squid’s esophagus (only three are...
